Again, we have a sort of honeycomb weathering. "Honeycomb weathering, also known as fretting, cavernous weathering, alveoli/alveolar weathering, stone lattice, stone lace or miniature tafoni weathering (Mustoe, 1982) is a form of salt weathering common on coastal and semi-arid granites, sandstones and limestones (Mustoe 1982)." https://en.wikipedia.org/wiki/Honeycomb_weathering
